MACHINE FOR CUTTING SOLES.

SPECIFICATION forming part of Letters Patent No. 647,888, dated April 1*?, 1900.

Application filed August 5, 1899.

To all whom t may concern/: i

Be it known that I, ALLIsoN Mouais STICK- NEY, of Medford, in the county of Middlesex and State of Massachusetts, have invented an Improved Machine for Cutting Soles or other Forms, of which the following is a Specification, reference being had to the accompany ing drawings, in ,which- Figure 1 is a side elevation, partly in section, of a portion kof onel of myimproved machines. Fig. 2 is a front elevation showing the samev parts shown in Fig. 1. Fig. 3 is a section on line 3 3 of Fig. l with certain parts removed. Figs. et and 5 are details described below. y

The machine shown is as to most of its parts fully described in myiPatentNo. 529,883, dated November 27, 1894, for my present invention is an improvement on the machine of that patent, and consists, mainly, in a new leader or form for guiding the knife-carrier in a path whichV conforms very nearly to the path of the knife, the great difference being that my new leader is a metal sheet with a sole-shaped aperture cut in it and a sinuous strip extending `along the edge of the soleshaped aperture instead of ametal sheet with a properly-shaped outline, as in my former patent. This new feature is especially important when the knife itself is guided by traveling about a form of sheet metal Whose periphery is the exact path of the knife, for the reason that the axis of the guide-roll can extend through the sheet-metal leader,which enables the leader to be supported along its outer periphery in the frame in which it is detachably secured instead of being supported from a point within its periphery, as in my former patent, and as it is essential that theV leader be of sheet metal it is obvious that it can be much better support /if it be, for example, a rectangular sheet/'with an aperture formed in it and a sinuous ystrip to engage the rolls than it could be if it were a strip whose periphery engaged the rolls and Which Was supported from a point within its periphery.

A second feature of my invention is the combination of my leader with a slide or its equivalent, by which the leader is connected to its supporting-frame in such a manner that Serial No. 726,236'. (No model.)

the leader can be moved in its supportingframe by a cam or the like, the purpose being to keep the leader stationary when the form -to be cut nearly corresponds in size' with the leader, but to move the leader in a direction the same as that of the knife when the knifeform is longer than the leader. In this way a leader of a given length may be used not only with knife forms of about the same length as the leader, but also with knife- 6o forms of practically all lengths used in the cutting of soles and taps.

In the drawings, A is the frame D isa rod which carries at its lower end the knife-form a and its holder a' and also 65 carries the arms G G', which sustain the stud g of the knife-carrier and the stud g,'through which the knife carrier is driven by the `grooved bar H, which is sustained by the arms 7L hl and moves bodily in its proper path by 7o mechanism in the casing J?, being guided by a slot in the bottom J' of that casing and ac-` tuated through the pulley at the top of that casing, all as more'fully described in my former patent, No. 529,883; but the casing J2 75 in my improved machine has added toit the brackets j, through which rods j' extend. These rods are fast at one end to cross-head jg, which is fast to rod D, and carry at their other end frame B2, so that when rod D is' 8o moved endwise (by lever d', as in Patent No. 529,883) frame B2, slide B', and internal leader B move with it toward and from `work-support A'. The properly shaped aperture through the rectangular sheet-'metal plate B 85 acts on the principle of a cam-leader to guide the knife-stud g in its proper path, while the knife g2 is guided in its path by the knifelform a, the knife, the knife-block, and the knife-carrier being as in Patent No. 529,883 9o and needing no description here except that the knife-block is movable slightly on the knife-carrier as the form a requires, while the stud g of the knife-carrier must move as leader B requires. 95

Leader B is connected by the thumb-nuts h to slide B', so that it may be removed and another leader of a different style or shape substituted. The slide B is mounted in ways h', fast to frame B2. Pinion c is fast loo koptfzrates to vibrate lever e and through-link on ashaft'c", (part of the usual driving mechanism for stud g,) and pinion c meshes with and drives gear c2, which is loose on a stud l gear d2. .The gear d2 is fast on shaft d3,i

which has its bearings in bracket d', and on the lower end of'shaft di' is secured av cam d4, Vwhich is adjustable on shaft d3 for the pur` pose hereinafter set forth. The cam d4 operatesabel-l-crank lever 6,'Whichis fulcrumed upon stud e', projecting from bracket e2, fast to frameA, and one arm of lever e carries a cam-roll 3,'engaged by camd and the other arm isformed with a T-shaped slotef, in

which a stud e5 is adj ustably secured. Upon the stud e5 is pivoted one end of a link f, the

' other end of which is pivotall'y connected at f to an extension'b2 of slide B. The cam d4 I f to lmovefsl-ide B; and leader 1B to and froyin p -a line lengthwise ofthe sole-shaped hole onA l y u openingin leader B, "lengthwiseof lthesole 3o mentof theknife-carrie-r.

The above-described ymechanism is simple and rcompact and easily adjusted, but, as will be obvious, may be largely varied.
